Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)
The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ...
Formal calibration methodology for CFD models of naturally ventilated indoor environments
(Elsevier, 2012-08-31)
Well planned natural ventilation strategies and systems in the built environments may provide healthy and comfortable indoor conditions, while contributing to a significant reduction in the energy consumed by buildings. ...
Modelling of fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-03-04)
This paper presents a computational methodology for frictional contact mechanics of the pressure armour layer in flexible risers. This will allow, for the first time, quantification of key fretting variables, such as contact ...
Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: a critical review
(Elsevier, 2017-01-06)
Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its ...
Development of a Global Energy Management System for non-energy intensive multi-site industrial organisations: A methodology
(Elsevier, 2017-01-25)
For multi-site organisations, informed decision making on capital investment aimed at improving energy performance and cutting carbon emissions, across a global site base, is a complex problem. This work presents the ...
Influence of seasonal circulation on flushing of the Irish Sea
(Elsevier ScienceDirect, 2009-12-16)
We applied a three-dimensional general ocean and coastal circulation model to the Irish Sea in order to determine water renewal time scales in the region. The model was forced with meteorological data for 1995, a year with ...
Stone column effectiveness in soils with creep: a numerical study
(Taylor & Francis, 2016-03-16)
While it is well established that vibro stone columns reduce primary settlement and improve bearing capacity, their effect on creep compression has largely been overlooked to date. However, with increasing pressure to ...
Use of zeolite with alum and polyaluminum chloride amendments to mitigate runoff losses of phosphorus, nitrogen, and suspended solids from agricultural wastes applied to grassed soils
(Crop Science Society of America, 2015-09-16)
Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products (DBP), which are potentially harmful to human health. This study ...
The potential for the use of waste products from a variety of sectors in water treatment processes.
(Elsevier ScienceDirect, 2016-07-21)
This review examines the utilisation of waste products from three sectors (industry, agriculture, and construction and demolition) in filters for the removal of contaminants from water. Sand is commonly used in drinking ...
Statistical grain size effects in fretting crack initiation
(Elsevier, 2016-09-20)
A crystal plasticity computational framework is developed and validated to investigate the microstructure sensitivity of crack initiation in fretting. Randomly distributed microstructure geometries are incorporated into a ...
